I AM REMAKING ANOTHER VERSION OF THIS VIDEO AND PLANNING ON RELEASING IT ON 1/26/2011!----------------------------------------­----------Here is a simple guide to unlocking some of the best perks' pro versions as fast as you can and hopefully with some ease as these perks work together. The 4th combination that I mentioned at the end is using Hardline + Hardened + Hacker. That is another nice combination if you find yourself needing one of those pro versions as well. Let me know if this tutorial helped out!----------------------------------------­--------------------SUBSCRIBE TO MY CHANNELhttp://youtube.com/Joshgt2
